Nb4OTe9I4: a one-dimensional chain compound containing tetranuclear oxygen-centred niobium clusters

Abstract
The new one-dimensional chain compound Nb4OTe9I4 is prepared; its structural key feature is a distorted tetrahedral oxygen-centred cluster of niobium atoms with terminal iodine atoms and ditelluride-bridged edges; the individual clusters are linked to a one-dimensional chain by isolated Te atoms.
